atan2 will take 2 arguments to help this exact situations. atan takes x and y, which are basically cos (a) and sin (a). The atan2() function in C++ returns the inverse tangent of a coordinate in radians.

The only languages I have found that do combine them are Mathematica ArcTan and Common Lisp atan. Matlab atan2= 2.8438364863237604. C atan2= 2.8438364863237608.
